It eliminates split horizon issues without increasing the likelihood of routing loops.

It requires the configuration of the encapsulation command on the subinterface.

Which two statements regarding multipoint subinterfaces are true? (Choose two.)

A single multipoint subinterface is used to establish PVC connections to multiple physical interfaces on remote routers.

Each multipoint link is in its own subnet.

The physical interface does not have an IP address.

Split-horizon is disabled allowing routing updates to be re-transmitted on every subinterface.

Multipoint subinterfaces require the encapsulation frame-relay command to be issued individually for each subinterface to operate correctly.

Which three actions does a Frame Relay switch perform when it detects an excessive build-up of frames in its queue? (Choose three.)

puts a hold on accepting frames in excess of the CIR

drops frames from the queue that have the DE bit set

reduces the number of frames it sends over the link

re-negotiates flow control with the connected device

sets the FECN bit on all frames it receives on the congested link

sets the BECN bit on all frames it places on the congested link

Refer to the exhibit. Which two statements are true given the output shown? (Choose two.)

The IP address of the local Frame Relay interface is 172.16.1.4.

The local DLCI number is 401.

Inverse ARP is being used on this connection.

This interface is in the active state and in the process of negotiating configuration parameters.

Multicast is not enabled on this connection.

Refer to the exhibit. When troubleshooting a Frame Relay connection, an administrator entered the show interfaces s0/0 command and received the output shown in the exhibit. What are two probable reasons for this problem? (Choose two.)

The cable between the CSU/DSU and the router is disconnected.

The serial 0/0 interface is shutdown.

The router is not configured for the same Frame Relay PVC as the switch.

The LMI type on the Frame Relay switch is NOT ANSI.

The address of the Frame Relay switch is not in the routing table.

Refer to the exhibit. What three items can be concluded from the output shown in the exhibit? (Choose three.)

The output in the debug frame-relay lmi command will indicate status 0x2 for DLCI 18.

DLCI 16 was correctly programmed on the switch, but the remote router may be misconfigured.

The frame relay switch is sending LMI status messages about DLCI 16 to the Singapore router.

Congestion has been experienced on DLCI 16.

Congestion has been experienced on DLCI 18.

Some packets have been set to be dropped if congestion is experienced on the PVC.

Refer to the exhibit. What can be determined about the Frame Relay switch from the output shown?

It is currently not transmitting data.

It is in the process of establishing the PVC.

It has put a hold on processing frames in excess of the CIR.

It is experiencing congestion.

Which statement describes parallel data communications?

Digital data is broken into 8-bit chunks (bytes) and transmitted from one entity to another bit by bit.

Digital data that is transmitted over a parallel connection is not affected by clock skew or crosstalk.

Digital data is transmitted from one entity to another via the use of a bus that consists of multiple wires, each carrying one bit of the data sample.

Digital data is transmitted via the use of two loops of wire, one in each direction.

Refer to the exhibit. Router R2 is part of a Frame Relay network that uses OSPF for IP routing. After the commands that are shown are entered, R2 will not exchange OSPF information correctly. What is the likely cause?

The frame-relay map command requires the broadcast keyword.

The DLCIs on each end of the PVCs are not identical.

The R2 S0/0/0 interface has not been brought online.

The LMI or Inverse ARP or both are not working.

Refer to the exhibit. All of the locations are going to be connected by a new WAN solution. If Frame Relay is selected as the solution, how many physical circuits are required to create a Frame mesh topology?
